I'd agree. Actually, the first thing I'd do, were it my machine, is reboot it
and run memtest86 overnight. CPU thrashing like that may indicate bad RAM.
If the RAM checks out, I'd like to see the EXPLAIN ANALYZE for some of the
longest-running queries, and for those INSERTS.
Also, is the new machine running Software RAID?
